Explanation:
Many  
stars like our  
Sun were formed in  
open clusters.  
 
The above open cluster,  
M11, contains thousands of stars and is just over  
three thousand  
light years distant.  
 
The stars in this cluster all formed 
together about 150 million years ago.  
 
The bright young stars in  
M11 appear blue.  
 
Open clusters, also 
called galactic clusters, contain fewer and younger stars than  
globular clusters.  
 
Also unlike globular clusters, 
open clusters are generally confined to the plane of  
our Galaxy. 
 
M11 is visible with binoculars towards the constellation of Scutum.
